Plain 12.19-inch rotors and internal parking shoes provide the service and parking brakes. The required 2.75- or 2.81-inch offset and original C-clip retention must be confirmed on the actual housing; front-spindle options cannot prove the rear application. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-12570\u003c\/li\u003e\n\u003cli\u003eType: D154 Rear Parking Brake Kit\u003c\/li\u003e\n\u003cli\u003eCalipers: D154; 2 pistons per caliper; Black Powder Coat.\u003c\/li\u003e\n\u003cli\u003eCaliper bore sizes: 1.12, 1.12 inches.
